Description
Technical field
The utility model relates to circuit interconnection technique field, especially a kind of hollow rotary shaft cover that is used for rotary electric connector.
Background technology
Electric rotary connector be a kind of can be at the electric connector of transmission signals under the rotary state and power supply power, in rotary course, twisting and damage can not take place in the cable that is used for transmission signals and power supply power.The main composition member of electric rotary connector is electric slip ring and brush, utilize the relative rotational slide between electric slip ring and the brush to contact the transmission of finishing signal and power supply power, the electric slip ring of existing rotary electric connector all is that insulation is assemblied on the slip ring axle, realize electric slip ring relatively rotating by the slip ring axle with respect to the rotation of brush with respect to brush, thereby transmission signals and power supply power under the realization rotary state, existing slip ring axle is traditionally arranged to be hollow-core construction, and lead is arranged in the endoporus of slip ring axle.But some devices that need connect need be installed other parts (as cradle head etc.) in the endoporus of described slip ring axle when using rotary electric connector to connect, and above-mentioned slip ring axle can not satisfy its requirement, makes its scope of application that limitation be arranged.
Summary of the invention
The purpose of this utility model is to provide a kind of hollow hollow rotary shaft cover that is used for rotary electric connector, overlaps the problem that in the slip ring axle other parts can not be installed to solve the existing hollow rotary shaft that is used for rotary electric connector.
For achieving the above object, the utility model adopts following technical scheme: a kind of hollow rotary shaft cover that is used for rotary electric connector, it axially is provided with at least one crossed beam trunking the outer wall upper edge that this hollow rotary shaft that is used for rotary electric connector overlaps, and the bottom land of described crossed beam trunking and the described internal face that is used for the hollow rotary shaft cover of rotary electric connector form thin-walled portion on jacket wall.
One end of the described hollow rotary shaft cover that is used for rotary electric connector is provided with and is used for the clutch shaft bearing seat that is sealed and matched with bearing inner race, the other end is provided with second bearing pedestal that is used for the bearing inner race matched in clearance, and described second bearing pedestal is arranged on the thick wall part of described crossed beam trunking.
The described two ends that are used for the hollow rotary shaft cover of rotary electric connector are respectively arranged with screwed hole.
The described thick wall part that is used for the hollow rotary shaft cover of rotary electric connector is provided with and is used for only revolving the keyway that cooperates with seal.
The end that the described hollow rotary shaft that is used for rotary electric connector puts second bearing pedestal is provided with locating shoulder, the described thick wall part that is used for the hollow rotary shaft cover of rotary electric connector.
Because the hollow rotary shaft that is used for rotary electric connector of the present utility model is enclosed within on its jacket wall wire casing is set, the slip ring axle of existing inner cabling is changed into outside cabling, so just abdicated slip ring axle volume inside, can be used to the parts that other need be installed are installed, increase the range of application of electric rotary connector.
Further, the clutch shaft bearing seat that is sealed and matched at an end setting and the bearing inner race of described hollow shaft sleeve, can be by bearing with the described corresponding end sealing that is used for the hollow rotary shaft cover of rotary electric connector, internal structure to hollow shaft sleeve plays a protective role, the other end is provided with second bearing pedestal with the bearing inner race matched in clearance, in use, can the lead in the described crossed beam trunking be drawn, thereby connect with corresponding device by the gap between bearing and the described rotary sleeve; An end that is provided with the clutch shaft bearing seat at the described hollow rotary shaft cover that is used for rotary electric connector is provided with screwed hole, can be used for installing bearing (ball) cover, an end that is provided with second bearing pedestal at the described hollow rotary shaft cover that is used for rotary electric connector is provided with screwed hole, can be used for fixedlying connected with the mount pad (as mounting panel) of electrical connector plug or socket; Thick wall part at the described hollow rotary shaft cover that is used for rotary electric connector is provided with keyway, can be used for only revolving with seal (insulating case) cooperating, thereby make the two connection more reliable; The end that the described hollow rotary shaft that is used for rotary electric connector puts second bearing pedestal is provided with locating shoulder, can be used for cooperating with the location or the bracing or strutting arrangement of other structure (as the above-mentioned electrical connector plug or the mount pad of socket).
